## Description

lastiseal is a unique, off-standards, sealing finish for bricks, concrete, mortar, stones and porous building materials benefits from a guaranteed waterproofing of 15 years. This water-based, polyester-polymer and polyurethane coating, penetrates up to 10.2 cm in brick, mortar, plaster, concrete and masonry. lastiseal fills the pores of the internal bond, the substrate and polymerization of hard plastic inside. A surface will seal the water and unless too rough, pearl for years to come. Unparalleled protection and longevity? Unlike paint or putty, lastiseal will not change the appearance or your brick, concrete or masonry. lastiseal does not form a surface film and leaves no glossy or colored finish on the surface. After drying (24 hours), the seal is almost permanent. Safe, Indoor/Outdoor Seal: Brick Walls and Floors, Indoor and Outdoor, Concrete Cellar, Concrete, Pavers, Driveways, Pool Decks, Patios, Stones, Tiles, Mortar, Koi Pound, Porous

Review: This is good stuff, it sprays on very nice and covers well soaks in and drys fairly quick. No reason to put 2 coats on, the second coat just beads up and runs off. I Put it on old brickwork that I had to do tuck pointing on. It sealed the new mortar and old brick with no issues. I put it on with the temp just at the low end 50*and it still dried pretty fast under 30 min. The old brick really sucked up the sealer so I only covered about 30 sq ft in 1/2 gallon. It is a bit more expensive than other sealers but if it lasts as long as it advertises then it’s well worth the cost, I will buy more in the spring when I redo the rest of the brick on the house
Review: Product is easy to use, but wear old clothes when applying. Sealed chimney and stopped leak.... I think!

### ⭐⭐⭐⭐⭐ Review
*by S***H on 18 May 2024*

I used this product back in 2018 when my house was built and today in 2024 my concrete sidewalks look like the day they were poured. All of my neighbors: crumbling, dirty, falling apart, and pitted. I went ahead and bought another gallon and coated all of my wood under my porches and even my unfinished basement. Not having to worry for 15 years is an incredible feature even counteracting the slightly higher price of this product.
